[R] Ecological Niche Modelling on R [SEC=UNCLASSIFIED]
Hi Miltinho, There is a brief review on issues about and a new method for modelling presence-only data in DOI 10.1007/s10531-007-9270-7. Hope it is useful.

I think that "grasp" and "adehabitat" packages could help me on these tasks. My input layers are on ASC format, and the record of species is a data-frame with X, Y, name of species. Note that in general we don?t have real absence data. Could someone give some advice how can I use "grasp" and/or "adehabitat" to generate my predictive models?
